Abstract: The effect of integrated nutrient management (INM) on crop yield and passive pools of soil organic carbon (SOC) under groundnut-wheat cropping sequence of a Haplustepts was studied in a long-term field experiment initiated during kharif 1999 at the Instructional Farm, JAU, Junagadh, Gujarat. Effect of varying doses of N, NP, NPK with FYM, Zn, S and Rhizobium on passive pools of SOC viz., humic acid, fulvic acid and humin after 12th year of groundnut-wheat crop sequence was studied. The result revealed that application of 50% NPK + FYM @ 10 t ha-1 to groundnut and 100% NPK to wheat significantly increased crop yield and humic acid, fulvic acid and humin. Integrated use of FYM with chemical fertilizers or use of FYM alone exerted significant effect on the passive pools of soil organic carbon. The crop yield and among forms was positively and highly significantly correlated with passive pools.
